EGBERT H. GOLD, OF CHICAGO, ILLINOIS.

CAR-HEATING SYSTEM.

Application filed February 27, 1915.

T 0 all whom it may concern Be it known "that I, EGBERT H. GOLD, a citizen of the United States, residing at Chicago, in the county of Cook and State of IlllIlFlS, have invented certain new and useful Improvements in Car-Heating Systems,

of which the following is a specification.

My invention relates to a heating system i for railway cars and the invention has for occasion requires, to supplement the action of the hot water coils, which latter provide the sole means for heating the car under ordinary conditions. In a system of this 'sort the water coils extend the length of the car and are arranged so that besides supplying heat to all parts of the car, they prevent the water supply pipes and fittings of the car from becoming frozen up in severe weather. Because of this function of the water circulating coils, it is essential that the steam circulating coils, or at least certain of them, should be incapable of being supplied with medium unless the water coils are in operation. Otherwise the attendant might, by using the steam circulating system alone, or certain parts of it, bring about a freezeup of some of the water supply pipes or other fixtures containing standing water. I'he supply pipe or pipes for the steam circulating coils are, therefore, arranged so that they may be closed without affecting the how of steam to the heater for the hot water system, while, on the other hand, it is not possible to introduce steam into the steam circulating coils, or at least into steam coils which the attendant might use instead of the water coils for heating the car as a whole, unless steam at the same time is sup plied to the water heater, thereby making ing the cost of installation and repairs.

A further object is to provide an arrange- Specification of Letters Patent.

ment whereby the controlling devices for the steam circulating coils are kept warm enough so that they will not freeze even when this part of the system is inactive, as will ordinarily be the case most of the time.

A further object of the invention is to provide a fitting adapted to surround the train pipe of the car heating system to which fitting certain of the other elements of the heating system may be attached and which provides means through w iich said elements are put into communlcaticn with each other. The lnvention is illustrated, in a preferred embodiment, in the accompanying drawings showing the said improvements employed in connection with a heating system of the type above described. I

Figure l is a. diagrammatic view of a car heating system of this type. Fig. 2 is a side elevation of a fitting which surrounds the train pipe and to which certain elements of the heating system are attached, as will be hereinafter described. Fig. 3 is a sectional plan on line 33 of Fig. Fig. 4 is a vertical cross sectional view on line 4- of Fig. 2. F g. 5 is a view, in perspective, of a group of devices for controlling the steam circulating coils attached to a fitting of the kind detailed in the preceding three figures. Fig. 6 is a side view of a modified form of fitting. Fig. 7 is a plan view of the same. Fig. 8 is a sectional View taken on line 88 of Fig. 7. Fig. 9 is a diagrammatic view,

similar to, Fig. 1, showing a modified arrangement of the steam. heating coils.

Like characters of reference designate hke parts in the several figures of the drawings.

A brief description will be first given of It i should be understood, however, that the improvements constituting my nvention,

the heating system shown in Fig. 1.

might be employed with car heating systems different from this particular system but which are constructed and operated in accordance with the same general principles. Referring to this figure, A represents the car, B the steam train pipe, C and D water circulating coils, and E the steam heater for the water circulating system, which, of

course, is ordinarily inclosed in a stove (not shown in the drawlngs). by means of which the water may be heated by a coal fire when E ...l w v fran'gement of the four-way valves being in tors N, N

receives steam from the train line B through a pipe F provided with a shut off valve Q. As stated, the water coils constitute the primary radiating units in the system and extend the length of the car on each side thereof and pass near all pipes, fittings and the like containing water and'locatcd so that the water therein is likely to freeze unless specially heated. lVhen additional heat is required in the car, itis obtainable from the steam circulating coils H, I, J, K, L and M, which may be supplied with steam singly or all together, asmay be desired. 1 The supply of medium to the coils H and I is con trolled by a vapor regulator N of the type shown in my Patent No. 987,567, March 21, 1911, which operates to maintain steam in the coils at a pressure approximating atmospheric pressure. These two coils are connected together and to the vapor regulator by a pair of four-way valves 0, O 111 an arrangement such as that shown in said Patent No. 987,567, whereby the coils may be put under steam either. singly or conjointly as required. The steam for coils H and I is supplied through a pipe P which is connected with the steam coils of heater E. By this arrangement it is impossible to use any of the steam coils unless the water system is in operation.

R is a fitting surrounding train pipe B,

with which pipe P is connected and to which the vapor regulator N is attached and also preferably a steam trap S. R is a similar fitting on the train pipe connected with fitting R by a pipe T and to which is attached a steam trap S and vapor regula- The vapor regulator N controls the supply of steam to coils L and M which are provided with a pair of four-way valves 0", G The vapor regulator N controls the steam supply to the circulating coils J, K, which are likewise provided with four-way valves designated 0*, 0 the arnamely, the fitting R. This device is illustrated in detail in Figs. 2 t0 4 inclusive. It consists of a tubular member 10 surrounding the train-pipe B and formed with lateral hollow projections 11 which are diagonally disposed with respect to the tubular memher and are joined underneath one end of the tubular member by a transverse hollow member 13. The transverse member is tapped on one side for the trap S and on the other for the supply pipe P. The hollow projecting members 11 are formed with taps in their sides and ends. Into one of the side taps is threaded the connecting pipe 1 1 of the vapor regulator N. The-opposite side tap is closed by a plug 15. The pipe '1 through the circulating coils.

the appropriate four-way valves 0, 0, etc.

.eltssun'iing that coils H and l are thus put into operation, steam passes from the steam coils of the water heater through pipe P to the fitting it, through the duct 16 on one side of the fitting into the vapor regulator N and thence through the coils H and l (or whichever one is open, if only one is open), the medium outfiowing through the vapor regulator in the manner described in my patent above referred to. lVhen the coils H and 1 are cut out again, which accomplished through the manipulation of the four-way valves 0', t), the ste. will con tinue to flow in small amounts through pipe P, duct 16 and the pipes 17 and 1S connecting the four-way valves with the vapor regulator; the amount of steam passing through this circuit being just sutlicient to keep the thermostatic member of the vapor regulator expanded. Ehe operation of the vapor regulator under these conditions is also described in my Patent No. 987,567. The heat derived from this small amount of steam, together with the heat radiated from the train pipe B in which, of course, the pressure is relatively high, is sufficient to keep the steam trap and the vapor regulator fr an freezing up even in very cold weather. With the steam circulatory system operative steam flows through the pipe T to the fi ting R. If ncne of the vapor coils associated with this fitting are active, just enough steam will pass through pipe T to keep the vapor regulators N, N and steam trap S from freezing. When one or more of these coils is opened up steam flows through pipe '1 in a volume appropriate to the amount, of active-radiating surface. The ;funct1on of the steam trapsS. S is to purge the medium of water ofcondensation before it is sent If the entire steam circulating system is cut. off, by clos ing valve Q, the proximity of the traps S, S and vapor regulators N, N, N to the fit tings R, R and the train pipe B prevents these devices from being clogged with ice.

A modified form of fitting is shown in Figs. 6 to 8 inclusive. The device shown in these figures is substantially the same as that detailed in Figs. 2 to inclusive,'e: cept that it is made in two parts, a lower part 19 and an upper or covered part 20, the

parts being fitted around the train pipe B and secured together by bolts 21. The lower part 19 is formed with the ducts and taps like those of the fitting previously described. In addition, the lower member 19 is formed with cars 22 connected by bolts 23 to a yoke 24 hung from the under frame 25 of the car.

In Fig. 9 I have shown a heating system constructed and operated upon the same general principles as the heating system shown in Fig. 1 but modified so as to be particularly suitable for a sleeping car containing state rooms, lavatories or smoking rooms which may require heateven when it is undesirable to heat, even with the water coils, the main or lierth section of the car. To meet this contingency certain portions of the car, for example the state room, the ladies lavatory and the smoking room, are provided with steam coils which can be supplied with steam directly from the train pipe so that these rooms may be heated even though the water circulating system inactive. The auxiliary steam heating coils for the main or berth section of the car, as in the system previously described, may be supplied with steam only when the water system is in operation. There is no danger that the attendant will attempt to use the auxiliary steam coils for the special compartments when the whole car needs heat, in place of the water coils, and thereby cause a freeze up in the system because the steam coils in the special compartments, the state rooms, lavatory and smoking room, will be so obviously ineffective for this purpose that no such mistake can be made.

The body of the car, in Fig. 9, is indicated at A, the smoking room at 32, the ladies lavatory at 33, the state room at 34;, and the berth section of the car at 35. The elements of the heating system, which are the same as in the arrangement of Fig. 1, are given corresponding reference charac' ters and will not be particularly described. The berth section 35 of the car is shown as provided with three auxiliary steam coils U, U, U which receive steam through pipe P and fitting 26, the control of these coils being efiected by vapor regulators N N and fourway valves 0, 0", 0 the arrangement and operation of which is the same as the corresponding devices in the Fig. 1 system. The ladies lavatory and the state room 34: are provided with steam coils V, V, supplied with steam directly from the train pipe B through acircuit 36 in which is arranged a vapor regulator and four-way valves 0 0 the arrangement of the fourway valves O, 0 being the same as that of four-way valves 0, 0 shown in Fig. 1, whereby either coil may be supplied singly or both together, in which latter case the medium flows first through one and then through the other.
